Over the course of the season, Broncos quarterback Drew Lock will make countless off-script plays such as buying time by leaving the pocket or scrambling for a third-down conversion. But to start a game, Lock is all about the script. He wants to drive to Mile High or ride the bus to a road stadium knowing what offensive coordinator Pat Shurmur’s first 10-12 calls will be. “I do enjoy it and I like to be able to go into the last couple nights (before a game) looking at the openers,” Lock said. Good for Lock that Shurmur is also pro-script. “All the way back to when I was with Coach (Andy) Reid in Philadelphia,” Shurmur said.
